Saltwater intrusion in the shallow aquifer in Martin and Palm Beach counties, Florida
W. B. Scott, L. F. Land, H.G. Rodis
1977, Water-Resources Investigations Report 76-135
Urban growth has been rapid in recent years in Palm Beach and Martin Counties, Fla. The withdrawal of large quantities of fresh ground water in the vicinity of the coast has reduced or locally reversed the natural seaward hydraulic gradient and, in places, allowed saltwater to advance landward in the...
Analog-model analysis of regional three-dimensional flow in the ground-water reservoir of Long Island, New York
Rufus T. Getzen
1977, Professional Paper 982
A three-dimensional analog model of the ground-water system beneath Long Island, N.Y., provides a practical means for studying anisotropic flow on a regional scale. Constructional and operational techniques influence the simulation almost as much as model design does. Usefulness and accuracy of the model depend on (1) inherent and practical...

Water resources data for Massachusetts and Rhode Island, water year 1976
Water Resources Division, U.S. Geological Survey
1977, Water Data Report MA-RI-76-1
Water-resources data for the 1976 water year for Massachusetts and Rhode Island consist of records of stage, discharge, and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 109 gaging stations, month end contents for 15 lakes and reservoirs, water quality...

Preliminary study of subsurface wastewater movement in and near Grand Teton National Park, Wyoming, through October 1976
Edward Riley Cox
1977, Open-File Report 77-275
Investigations were made by the U.S. Geological Survey in cooperation with Teton County, Wyoming and the National Park Service to determine the effects on nearby lakes and streams of percolating wastewater effluent at three sites in and near Grand Teton National Park. Observation wells were drilled at two of the...

Preliminary report on the coal resources of the Dickinson area, Billings, Dunn, and Stark Counties, North Dakota
Michael L. Menge
1977, Open-File Report 77-482
The Dickinson area is underlain by the coal-bearing Fort Union Formation (Paleocene). The Fort Union in this area contains nine potentially economic coal beds. Five of these beds are, either all or in part, shallow enough to be economically extracted by conventional strip-mining methods, while the remaining four deeper beds...

Physical, chemical, and biological relations of four ponds in the Hidden Water Creek strip-mine area, Powder River Basin, Wyoming
David J. Wangsness
1977, Water-Resources Investigations Report 77-72
The Hidden Water Creek area in Wyoming was mined from 1944 to 1955 and abandoned. The open pits filled with water and pond-type ecosystems developed. Light was transmitted to greater depths within two control ponds located outside the mine area. The lower light transmittance in the ponds within the mined...
Hydrology of the Creeping Swamp Watershed, North Carolina with reference to potential effects of stream channelization
M.D. Winner, C.E. Simmons
1977, Water-Resources Investigations Report 77-26
Hydrologic data were collected for four years at six sites in the Creeping Swamp watershed in eastern North Carolina in a preliminary effort to study the effects of stream channelization on the hydrology of a small watershed. A water-budget evaluation for pre-channelized conditions showed that runoff accounts for about 17...
Paleozoic-Mesozoic boundary in the Berry Creek Quadrangle, northwestern Sierra Nevada, California
Anna Martta Hietanen
1977, Professional Paper 1027
Structural and petrologic studies in the Berry Creek quadrangle at the north end of the western metamorphic belt of the Sierra Nevada have yielded new information that helps in distinguishing between the chemically similar Paleozoic and Mesozoic rocks. The distinguishing features are structural and textural and result from different degrees...

Ground-water resources along the Blue Ridge Parkway, North Carolina
M. D. Winner Jr.
1977, Water-Resources Investigations Report 77-65
The best areas to develop ground water along the Blue Ridge Parkway in North Carolina are in broad draws and in stream valleys where draws open to the valleys. Saprolite thickness in these places can exceed 50 feet and provide adequate ground-water storage; draws are topographic expressions of fracture zones...
